1. Field of the Invention
The present invention relates to server chassis, and more particularly to a server chassis with an air flap apparatus for preventing air outside the server chassis from flowing into the chassis to interfere with the normal air flow therein.
2. Description of Related Art
Generally, an opening is defined at one end of a server chassis via which a functional module is inserted into or drawn out of the server chassis. When the functional module is removed from the chassis, the corresponding opening of the chassis should be shielded, otherwise the air outside the server chassis flows in to interfere with the normal airflow in the sever chassis and possibly impair heat dissipation in the server. A shielding apparatus is typically attached to the chassis by multiple screws, it makes the installation and detachment of the shielding apparatus tedious.
What is desired, therefore, is a server chassis with an air flap apparatus conveniently shielding or exposing an opening in the server chassis.
An exemplary server chassis is provided for receiving a functional module therein. The server chassis includes a base with an opening defined in an end thereof for the functional module inserted therethrough, and an air flap apparatus engaging with the base. The air flap apparatus includes a shielding panel pivotably attached to the base, and a resilient member connected to the base and the shielding panel to urge movement of the shielding panel.

Referring to FIGS. 1 and 2, a server chassis in accordance with an embodiment of the present invention is provided for receiving a pair of first functional modules 100 and a pair of second functional modules 200 via openings defined in a rear end thereof. The server chassis includes a base 10, a mounting bracket 20, a pair of first air flap apparatuses 30, a pair of second air flap apparatuses 40, and a cover 50.
Referring also to FIG. 3, the base 10 includes a bottom panel 12, a pair of parallel side panels 14 vertically extending upward from opposite side edges of the bottom panel 12 respectively, and a pair of parallel partitioning panels 16 vertically extending upward from bottom panel 12. Each of the partitioning panels 16 includes a pair of pivoting holes 163 defined therein near a rear edge thereof, and a pair of posts 165 extending perpendicularly outward from a same side adjacent to the pivoting holes 163 toward the other partitioning panel 16. A pair of engaging portions 167 respectively extends from the rear edges of the partitioning panels 16 towards each other. A through hole 1674 is defined in each of the engaging portions 167.
Referring also to FIGS. 4 and 5, the mounting bracket 20 includes a top wall 22 and a pair of sidewalls 24 vertically extending down from opposite side edges of the top wall 22. The top wall 22 includes a pair of mounting mechanisms configured for correspondingly engaging with the first air flap apparatuses 30. Each mounting mechanism includes a pair of first tabs 222, two pairs of second tabs 224, a pair of locating portions 226 and a pair of blocks 228 extending down from the top wall 22. The second tabs 224, the locating portions 226, and the blocks 228 are arranged between the first tabs 222. A pivoting hole 2221 is defined in each first tab 222. A fixing hole 2241 is defined in each second tab 224. A snapping hole 2261 is defined in each locating portion 226.
Each first air flap apparatus 30 includes a shielding panel 32, a pair of torsion springs 34, and a pair of shafts 36 for passing through the torsion springs 34. Each shielding panel 32 includes a pair of pivoting portions 322 respectively extending from top ends of opposite side edges thereof. A pair of arms 341, 342 respectively extends from opposite ends of each torsion spring 34.
Referring also to FIG. 6, each second air flap apparatus 40 includes a shielding panel 42 with a pair of pivoting portions 422 respectively extending from ends of opposite edges thereof, and a coil spring 44 attached to the shielding panel 42. A protruding portion 424 is formed on a side surface of the shielding panel 40 with a connecting hole 4241 defined therein. The coil spring 44 includes a pair of hooks 442 defined at opposite ends thereof.
Referring also to FIGS. 7, 8 and 9, in assembly, each air flap apparatus 30 is mounted to the mounting bracket 20 in a way as described herebelow: Each shaft 36 passes through the corresponding torsion spring 34, then, the shafts 36 are respectively snappingly engaged in the fixing holes 2241 of the second tabs 224 of the mounting bracket 20. The arms 341 of the corresponding torsion springs 34 are fixed in the snapping holes 2261 of the locating portions 226 of the mounting bracket 20. The pivoting portions 322 of the shielding panel 32 are pivotably received in the pivoting holes 2221 of the corresponding first tabs 222 of the mounting bracket 20. The arms 342 of the torsion springs 34 abut against the outside surface of the shielding panel 32. The blocks 228 abut against the inside surface of the shielding panel 32.
Each second air flap apparatus 40 is mounted to the base 10 in a way as described below. The pivoting portions 422 of the shielding panel 42 are pivotably received in the pivoting holes 163 of the corresponding partitioning panels 16 of the base 10. The hooks 442 of the coil spring 44 are respectively engaged in the through hole 1674 of the engaging portion 167 of the partitioning panel 16 and the connecting hole 4241 of the portion 424 of the shielding panel 42. The shielding panel 42 is pulled by the coil spring 44 to abut against the post 165 of the corresponding partitioning panel 16.
The mounting bracket 20 is secured to the base 10 with the sidewalls 24 respectively in tight contact with inside surfaces of the side panels 14 of the base 10. The first air flap apparatuses 30 are respectively disposed between the sidewalls 24 of the mounting bracket 20 and a corresponding one of the partitioning panels 16. Finally, the cover 50 is disposed on the mounting bracket 20.
When a first functional module 100 is pushed into the server chassis through one of the openings shielded by one first air flap apparatus 30, the shielding panel 32 of the air flap apparatus 30 is urged to pivot about the pivoting portions 322 thereof. Thus, the opening is exposed. The arms 342 of the torsion springs 34 of the air flap apparatus 30 are urged to move towards the corresponding arms 341 so that the torsion springs 34 are deformed. When a second functional module 200 is pushed into the server chassis through an opening shielded by a second air flap apparatus 40, the shielding panel 42 of the air flap apparatus 40 is urged to pivot about the pivoting portions 422 thereof. Therefore the opening is exposed. The coil spring 44 is elongated and deformed.
When the first functional module 100 is drawn out of the server chassis to move away from the shielding panel 32 of the first air flap apparatus 30, the corresponding torsion springs 30 are restored and the arms 342 urge the shielding panel 32 to pivot outwards until the shielding panel 32 abuts against the corresponding blocks 228 of the mounting bracket 20. Thus, the corresponding opening is shielded by the shielding panel 32. When a second functional module 200 is drawn out of the sever chassis to move away from the second air flap apparatus 40, the corresponding coil spring 44 is restored and the shielding panel 42 is pulled to pivot outwards until the shielding panel 42 abuts against the corresponding posts 165 of the partitioning panels 16. Thus, the corresponding opening is shielded by the shielding panel 42.
